MATTRESS-BEATING IJACHNE.

Application led December 8, 1920. Serial No. 429,283.

To all 'to/0m t may concern:

Beit knownthat I, GUsrAv A. AICHER, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented a new and useful Improvement in a Mattress-Beating Machine; of which the following-is a specification.

My invention relates' to improvements in ya mattress beating machine wherein a resiliently and reciprocating beating element opcrates in conjunction with a movable mattresssupporting element to subject different portions of the surface of a mattress thereon to the reciprocations of said beatingv stick. j

The primary objects of myinvention is to provide anew and improved mattress beating machine. e r

A; further object of the invention is to provide an improved device ofthe `character described having improved means for yadjusting the position of the stroke of the beating stick relatively tothe adjacent surface of the `mattress whereby the force of impact of said stick may be altered.

Another obj ect of the invention is to provide improved means formoving the mattress relatively to the beating stick whereby different portions of said mattress may be engaged and beaten by said stick.

` A still further object of the` invention is to provide an improved driving means for the reciprocating stick whereby said stick may be "automatically n disconnected from positive connection with said drive during they lower or operating portion` of the reciprocations of said beating stick to deliver' aresilient blow of said mattress.`

I accomplish these several objects by means of the improved device disclosed in the drawings forming a part of the present specification, wherein like characters of reference are used to designate similar parte throughout the said specification and drawings. and in which :w-

Fig. yl is a broken front elevation of the improvedvmac-hine;

F ig. 2 is a broken side elevation of the ymachine with themattress partly in section to bdisclosefthe operation of the beating stick' f Fig. B is an enlarged, broken side elevation of the reciprocating mechanism `disclosing the manner in which reciprocations are imparted to the beating stick; and

Figi -1 is an enlarged vertical sectional view taken on line 4-4; of Fig. 3 is the direction indicated.

Referring to the drawings the numeral v1 is used to designate ar supporting table having an upwardly extending portion 2supporting an upper rigid 'bearing member 3 having preferably four vertically disposed bearings elin each corner thereof within which are slidablymounted fourrods .6 having a lower movable member 'l' rigidly secured to the lower ends thereof.

The member' 7 is provided with depending rods 8 slidably mounted in opposite ends of said member 7 and having rigidly connected between them a beating element 9, preferably in the form of a rod orstick.

Springs l1 are interposed between therod or beating element 9 and the lower member 7 whereby said beating element 9 is resiliently mounted, the purpose of which. will hereinafter be more fully set forth.

,llotatably mounted upon the upper member 3 is a `sheave 14- having `a pinion 16 connected theretoand meshing with a gear 17 on a shaft ,18 also rotatably and centrally mounted upon the member 3. .TheV shaft 18 is provided at its outer end with an annularly flanged discfl) having anarcuate slot 21 therein. A floating disc 22 is rotatably mounted upon theshaft 1S and within the annularly flanged disc 19 andv has a wrist pin 23 `rigidly connected thereto and proj oo jecting through the arcuate slot 2l;

A flexible connecting rod 24, preferably a leather strap or the like7 has one end rotatably connected to lthe `wrist pin 23 and the other end, after passing' under a transverse rod .26 in the approximate `center of the frame member 7, is fixed to one end of a threaded rodA 27 passing through a nut or internally threaded hand wheel A29 rotatably mounted between .Suitable supports 28 formed integral with the lowerframe member 7. whereby rotation of the wheel 29 will lengthen or shorten the distance between` the upper and lower members?)` and' 7,respectively, to adjust the beating impact between thebeating element 9 and the mat,- tress hereinafter more fully set forth.. i

ico

The sheave 14 is connected by a suitable driving belt 31 to a motor 32 whereby opd erationof themachine may bey obtained.

. 19 4in .the direction .vindicated .by `the .curved arrow lin Fig. 3 of tbedrawings. Asthe disc 19 rotatesthe. rear ,end ofthe arcuate slot .21 therein, which is substantially semicircular, engages the wristpin 23 and-carries. the same to the upper ,portion of its circular. path. After the `said wrist pin 23 passes the vhighest point ,in .its rotation it `is 'reeto fallthroughatbe slot 21 tothe loweri most vpointwithin its.path,.and this descent is assisted by .thetension under which `the springs ,12 :were placed, .acting in conjunction i-.wit'h v,the .weight .of .the .lowerl frame member 7. during rthe upward movement of said rvvrist1pin-2 l The descentof thewrist .pin' 23 .permits` a rapid constantly accelerating ,movement :of the beating ...element ,9 .and causes a resilient impactof, said element with'the` mattress 34 thereby .beating that/portion. or" said.mattress which v.lies 4directly .under the. said beating element 9j As that .portion .is lproperly beaten the carriage .33 with themattress 34 thereon lis .moved to .various positions under thereciprocating .beating elementA 9 until the desired condition is attained.

The impactof thestroke of the beating element.9withtheJnattress 34 may be adjusted `by :manipulation of .the wheel 29 which will .lengthen or shorten 'the flexible connecting rod 24-to the desired length.

For instance, if .a ,lightstroke isdesired vfor mattresseshaving a certain type of. stuffing or` fillingmaterial, the .wheel 29 is rotatedto shorten the connectingrod'24 which action will..,elevate the lower `or movable ,frame-member 'so.thatthe.mattressy 34 will ynotbeso deep-ly engaged while .said frame is in A.its .lowermost position.

The .carriage 33 with the mattress 34 thereon ismoved .about upon the table l to 5 expose different vportions of the surface .thereof to: the action. of the-beating elem ent 9.

Astheaction ottl'ieeleinentf) is 'very rapid it isy evident thatportions ot the stutling oit vthe .mattress 34v may be moved about and v equally distributed withinsaid mattress by n moving the .saine `whilebeing subjected to 11 in order to cushionl the blow or impact of the stick 9 with the ticking of the mattress 34 to prevent injuryto said ticking.

,Having .thus described my `-invention what I claim as new and desire to secure by Letters Patent is 1.
